I got a single-entry tourist visa for thailand, but after doing more research, I realized I will want to reenter thailand later and stay longer than the 15 days allotted for US citizens without visa by land.
Can I just go to any immigration office in Thailand and apply to be able to reenter Thailand for more than 15 days?
What is this called?
How much does it cost?
I have the same problem; did you get any answer/informtaion??
You can go to Thai Immigration and buy a re-entry permit before you exit. Costs 1K baht. But that only gives you the days left on your tourist visa. I think your best bet is to either fly back into BKK or get another 60 tourist visa from the country you are visiting. Air Asia has some cheap airfares into BKK from either PNH or KUL. This website might help you decide what is the best option for you. Good luck.
